About the city:

The City of Guanajuato is the Capital of the State of Guanajuato and home to the main campus of the University of Guanajuato. It is one of the most important colonial towns in Latin America and a UNESCO declared World Heritage Zone.

This City is located about 350 km (220 miles) NW of Mexico City. Guanajuato dazzles the visitor with the charm of its relaxed atmosphere, its cobblestone streets, its picturesque plazas and underground streets. While remaining a small provincial city, Guanajuato boasts a great number of attractions, from beautiful colonial buildings to modern museums, from silver mines to a university.

Guanajuato’s altitude, 2000 meters (6000 feet), ensures that the climate is always pleasant. The rainy season is from June to September.

Getting to Guanajuato:

By air: The nearest airport to Guanajuato is Bajio International Airport (BJX) that have direct daily flights to and from Mexico City, Monterrey, Tijuana, Atlanta, Dallas, Houston, and Los Angeles. From the airport you can get to Guanajuato by taxi (30km). Just down the hall from the arrival area you will find a booth selling tickets for the taxis. Ask for a ticket to Guanajuato City. The taxi ride takes about 30min., the fare is approximately 600 pesos; payments with US dollars are accepted but not with credit cards. In the hall, there is an ATM connected to the Plus and Cirrus networks and a Currency Exchange office. There is no public transportation from the airport to Guanajuato City.

Another airport close to Guanajuato is Guadalajara International Airport (GDL). From there, you can take a bus to Guanajuato. Take a taxi to the Bus Terminal of Guadalajara (“Central de Autobuses”); the fare is approx. 450 pesos and the trip takes at least 20 minutes depending on traffic conditions. ETN and Primera Plus offer a direct service from the Central Bus Station to Guanajuato, each with a frequency of about ten departures a day. Travel time is approximately 4 hours.

Another option is Mexico City International Airport (MEX). From there, you can take a bus to Guanajuato. Once you are outside the arrival area, go to any of the taxi stands and ask for a ticket to the Northern Bus Terminal (“Terminal Central del Norte”). Caution: there are several bus terminals in Mexico City. The trip takes at least 30 min., and the fare is about 300 pesos. Travel time is approximately 5 hours.

When you arrive to Mexico, you will fill out and keep the bottom part of your immigration form. Do not lose this, as you will have to return it at immigration when you leave.

By bus: Primera Plus and ETN are two first class bus companies operating routes to Guanajuato. Compared to Primera Plus, traveling with ETN is more comfortable due to a reduced number of seats in the bus (including 8 individual seats); Primera Plus is about 20% cheaper. In general wifi is available. For time schedules and ticket purchase, consult Primera Plus and ETN webpages. In the evening, as buses run less frequently, buy your ticket in advance if possible. Once you arrive at the bus station in Guanajuato, take a taxi. There are no taxi stands to buy tickets. You should pay directly to the driver. The ride should cost about 80-120 pesos.

By car: Take into account that due to limited parking space, daily traffic congestions and the peculiar topography of Guanajuato, a car is not an efficient mean of transportation within Guanajuato City. As road signs are often confusing or absent, consult a route planning device in advance (e.g. google maps or the SCT planner). Except if you are an experienced driver in Mexico, we advise against car renting.
